213 – WriteOutput
Figure 40 contains the values for the following example to write the state of
GPIOA to low:
$PLSC,213,A,0*61
The receiver outputs a response to this command. Figure 41 contains the
response for the above command.
For some further examples of this command:
Set GPIOA to low
Input command: $PLSC,213,A,0*61
Output response: $PLSR,213,1*1C
Set GPIOA to high
Input command: $PLSC,213,A,1*60
Output response: $PLSR,213,1*1C
GPIOA is not an output
Input command: $PLSC,213,A,1*60
Output response: $PLSR,213,0*1D
